Gravity: A Puzzling Force from Apples to Black Holes
Gravity is the force that pulls things together.
It's why things fall to the ground and planets orbit the sun.
Newton first realized it, and Einstein later explained that gravity bends the fabric of space and time.
Gravity is a weak force compared to others, yet it is dominant at large scales, shaping galaxies and black holes.
Scientists still struggle to understand how gravity works at the smallest level, even with theories like string theory.
Gravity is a fundamental force of nature.
Newton's law explained gravity in terms of attraction.
Einstein described gravity as the bending of spacetime.
Gravity is incredibly weak compared to other forces.
Scientists are working to unify gravity with other forces.
